Everyone's path to success is different.

For some, it's mostly linear. Others encounter more twists, turns, and bumps along the way.

While some like Steve Jobs and Richard Branson were already dominating the business world at 25, others like Larry Ellison and Mark Cuban took a little longer to hit their stride and saw their mid-20s as transformative years.

To illustrate how no two paths to success are alike, we've highlighted what 26 highly successful people were doing at age 25.

Donald Trump took over his father's real-estate-development company

Trump, a billionaire real-estate mogul, and animated TV personality, grew up wealthy. But as he told Forbes, his father wanted him to learn the value of money.

As a kid, his dad would take him to construction sites and have him and his brother pick up empty soda bottles to redeem for cash. He says that he didn't make much, but it taught him to work for his money.

At 25, the young real-estate developer was given control of his father's company, Elizabeth Trump & Son, which he later renamed the Trump Organization, according to Bio. He soon became involved in large, profitable building projects in Manhattan.

Hillary Clinton had just graduated from Yale Law School

At 23, Clinton began dating fellow Yale Law student Bill Clinton. She ended up staying at school an extra year to be with her boyfriend, and received her law degree in 1973, just before turning 25. Her boyfriend proposed marriage after graduation, but she declined.

That same year, Clinton began working at the Yale Child Study Center. Her first scholarly article, "Children Under the Law," was published in the Harvard Educational Review in late 1973, when she was 25.

After moving to Arkansas in 1975, Clinton agreed to marry Bill. She'd go on to become the first lady of Arkansas, the first lady of the US, a US Senator, and Secretary of State.

Larry Ellison was working odd jobs as a programmer

After moving to Berkeley, California, at 22, the college dropout turned billionaire Oracle founder used what he picked up in college and taught himself about computer programming. He found odd technical jobs at places like Fireman's Fund, Wells Fargo, and AMPEX until finally landing at Amdahl Corporation, where he worked on the first IBM-compatible mainframe system.

Before her name was known in every American household, Stewart worked on Wall Street for five years as a stockbroker. Before that, she was a model, booking clients from Unilever to Chanel.

"There were very few women at the time on Wall Street … and people talked about this glass ceiling, which I never even thought about," Stewart said in an interview for PBS's MAKERS series. "I never considered myself unequal, and I think I got a very good education being a stockbroker."

In 1972, Stewart left Wall Street to be a stay-at-home mom. A year later, she started a catering business.

"When I got to Dallas, I was struggling — sleeping on the floor with six guys in a three-bedroom apartment," Cuban writes in his book "How to Win at the Sport of Business." "I used to drive around, look at the big houses, and imagine what it would be like to live there and use that as motivation."

Richard Branson had already started the Virgin Records record label

At age 20, Branson opened his first record shop, then a studio at 22, and launched the label at 23. By 30, his company was international.

Those early years were tough, he told Entrepreneur: "I remember them vividly. It's far more difficult being a small-business owner starting a business than it is for me with thousands of people working for us and 400 companies. Building a business from scratch is 24 hours, 7 days a week, divorces. It's difficult to hold your family life together; it's bloody hard work and only one word really matters — and that's surviving."

Jeff Bezos had a cushy job in finance

At age 24, the future Amazon founder and CEO went to work at Bankers Trust developing revolutionary software for banking institutions at that time, according to "Jeff Bezos: The Founder of Amazon.com" by Ann Byers

Two years later, he became the company's youngest vice president.

J.K. Rowling came up with the idea for the Harry Potter series on a train

She started writing the first book that evening, but it took her years to actually finish it. While working as a secretary for the London office of Amnesty International, Rowling was fired for daydreaming too much about Harry Potter, and her severance check would help her focus on writing for the next few years.

During these years, she got married, had a daughter, got divorced, and was diagnosed with clinical depression before finally finishing the book in 1995. It was published in 1997.

Jay Z was already in the rap scene but was relatively anonymous

Born Shawn Carter, Jay Z grew up in a housing project in Brooklyn, New York, and became known as "Jay Z" at the age of 20.

For the next few years he appeared alongside various other rappers, but "remained relatively anonymous" until he founded the record label Roc-A-Fella Records at the age of 27 with two other friends. The same year, Jay Z released his first album, "Reasonable Doubt."

Kat Cole was a star Hooters employee

A star employee, at 19 she was asked by Hooters to go to Australia to help open a franchise location there, and she spent muc of her early twenties training global employees and managers, Fortune reports.

She never finished the bachelor's degree, although eventually she got her MBA, according to Fortune.

"I was lucky that Hooters wasn’t a more sophisticated company, because there’s no way someone my age would have had those chances," she said. "It wasn’t like people graduating from Ivy League schools were dying to get a corporate job at Hooters."

US Government

The first female US Secretary of State and current professor of International Relations at Georgetown University was launching her career in politics at 25 while also raising a family with then-husband Joseph Albright, according to Bio.

Albright graduated from Wellesley College in Massachusetts in 1959, where she majored in political science, and she began studying Russian and international relations while she raised twin daughters Alice and Anne in Washington, DC.

After moving to New York with her husband, Albright completed her education at Columbia University, where she earned a certificate in Russian studies in 1968 and her MA and PhD in public law and government by 1976.

During that time she impressed a former professor so much he encouraged Albright to enter politics, and she joined him in the West Wing as the National Security Council's congressional liaison, according to Bio.

Marissa Mayer had just started her job as Google's 20th employee

Google didn't have the sorts of lavish campuses it does now, Mayer said in an interview with VMakers: "During my interviews, which were in April of 1999, Google was a seven-person company. I arrived and I was interviewed at a ping pong table which was also the company's conference table, and it was right when they were pitching for venture capitalist money, so actually after my interview Larry and Sergey left and took the entire office with them."

Since everyone in the office interviewed you in those days, Mayer had to come back the next day for another round.

Burns overcame a tough upbringing in a New York City housing project to get a degree in mechanical engineering from the Polytechnic Institute of NYU and then a master's from Columbia University.

Since then she's been a Xerox lifer. She started as an intern at age 22 in 1980 and joined full time a year later after getting her master's. She rose rapidly through the ranks, working in various product development roles and was named CEO in 2009.

"When I came to work at Xerox, I just chose to work. Somebody said 'how about this?' And I said OK, and I would go do that in the lab," Burns said in an interview for the PBS documentary "Makers." "Then somebody said how about doing some business planning. Then I started leaning more towards larger global systems problems. And systems problems are the business."

Mark Zuckerberg's Facebook was cash positive for the first time and hit 300 million users

Zuckerberg had been hard at work on Facebook for five years by the time he hit age 25. In that year — 2009 — the company turned cash positive for the first time and hit 300 million users. He was excited at the time, but said it was just the start, writing on Facebook that "the way we think about this is that we're just getting started on our goal of connecting everyone."

Tina Fey was a childcare registrar at the YMCA before joining famed improv troupe Second City

After graduating from the University of Virginia, Fey moved to Chicago and hung around acting workshops and even worked as the childcare registrar at a YMCA before improv troupe Second City invited her to join.

Fey told The New Yorker that she joined Second City because she "knew it was where a lot of SNL people started," and in 1997 she sent scripts to "Saturday Night Live" producer Lorne Michaels, who then hired her as a writer.

Starbucks CEO Howard Schultz was a Xerox salesman

After graduating from Northern Michigan University, Schultz worked as a salesman for Xerox. His success there led a Swedish company named Hammerplast that made coffeemakers to recruit him at age 26.

While working for that company, he encountered the first Starbucks outlets in Seattle, and went on to join the company at age 29.

On his job in Xerox, Schultz writes in "Pour Your Heart Into It": "I learned more there than in college about the worlds of work and business. They trained me in sales, marketing, and presentation skills, and I walked out with a healthy sense of self-esteem. Xerox was a blue-chip pedigree company, and I got a lot of respect when I told others who my employer was ... But I can't say I ever developed a passion for word processors."

According to the Huffington Post, Winfrey was fired from the 6 p.m. news slot at Baltimore's WJZ-TV in 1977 at age 23.

In 1978, a 24-year-old Winfrey was recruited to co-host WJZ's local talk show "People Are Talking." While there, she also hosted the local version of "Dialing for Dollars."

Winfrey remained in Baltimore throughout her mid- and late-20s, until moving to Chicago in 1983 to host "A.M. Chicago" for WLS-TV.

Google Executive Chairman Eric Schmidt was building a deep background in computer science

Sheryl Sandberg had met mentor Larry Summers and was getting a Harvard MBA

60 Minutes

At age 25, Sandberg had graduated at the top of the economics department from Harvard, worked at the World Bank under her former professor, mentor, and future Treasury Secretary Larry Summers, and had gone back to Harvard to get her MBA, which she received in 1995.

She went on to work at McKinsey, and at age 29 was Summers' Chief of Staff when he became Bill Clinton's Treasury Secretary.

Her time at HBS was a ways before Google, but that experience helped her see the potential of the internet, she said in a commencement speech to HBS grads last year:

"It wasn't really that long ago when I was sitting where you are, but the world has changed an awful lot. My section, section B, tried to have HBS’s first online class. We had to use an AOL chat room and dial up service (your parents can explain). We had to pass out a list of screen names, because it was unthinkable to put your real name on the internet. And it never worked. It kept crashing … the world wasn't set up for 90 people to communicate at once online. But for a few brief moments though, we glimpsed the future, a future where technology would power who we are and connect us to our real colleagues, our real family, our real friends."
